Mars, one of the world's biggest food companies, has recalled chocolate bars and other products in 55 countries after a piece of plastic was found in a Snickers bar in Germany, according to a Reuters report.

All of the recalled products, which include Mars, Snickers and Milky Way bars, were manufactured at a Dutch factory in Veghel, a Mars spokeswoman said on Tuesday. They were sold in European countries including Germany, France and Britain, and in certain countries in Asia.

"We cannot be sure that this plastic was only in that particular Snickers," a spokeswoman from Mars Netherlands said. "We do not want any products on the market that may not meet our quality requirements, so we decided to take them all back."

It was not immediately clear how much the complex recall would cost the company, which is unlisted and therefore does not disclose detailed financial information. The spokeswoman declined to comment on financial implications of the recall, which is the first to affect the factory.

Mars Netherlands said it was working closely with the Dutch food safety authority on the matter, according to a statement.

The recall affected all Mars and Snickers products, Milky Way Minis and Miniatures as well as certain kinds of Celebrations confectionery boxes with best-before dates ranging from June 19, 2016 to Jan. 8, 2017. Those dates may not be the same in other countries, the spokeswoman said.
